ARM: proc-v7: move CPU errata out of line

Rather than having a long sprawling __v7_setup function, which is hard
to maintain properly, move the CPU errata out of line.

While doing this, it was discovered that the Cortex-A15 errata had been
incorrectly added:

	ldr	r10, =0x00000c08	@ Cortex-A8 primary part number
	teq	r0, r10
	bne	2f
/* Cortex-A8 errata */
	b	3f
2:	ldr	r10, =0x00000c09	@ Cortex-A9 primary part number
	teq	r0, r10
	bne	3f
/* Cortex-A9 errata */
3:	ldr	r10, =0x00000c0f	@ Cortex-A15 primary part number
	teq	r0, r10
	bne	4f
/* Cortex-A15 errata */
4:

This results in the Cortex-A15 test always being executed after the
Cortex-A8 and Cortex-A9 errata, which is obviously not what is intended.
The 'b 3f' labels should have been updated to 'b 4f'.  The new structure
of:

	/* Cortex-A8 Errata */
	ldr	r10, =0x00000c08	@ Cortex-A8 primary part number
	teq	r0, r10
	beq	__ca8_errata

	/* Cortex-A9 Errata */
	ldr	r10, =0x00000c09	@ Cortex-A9 primary part number
	teq	r0, r10
	beq	__ca9_errata

	/* Cortex-A15 Errata */
	ldr	r10, =0x00000c0f	@ Cortex-A15 primary part number
	teq	r0, r10
	beq	__ca15_errata

__errata_finish:

is much cleaner and easier to see that this kind of thing doesn't
happen.
